My current bike packing rig is a Surly Big Dummy with aBBS02 mid drive and a Q128 slow wind geared hub up front. It’s a heavy awkward beast but the nicest ride ever. This is my third iteration of dual motors on this bike and the best so far. I run the mid drive all the time in pedal assist mode...

video is about removing controller on a LECTRIC ebike of the same folding configuration. I’m pretty sure your controller will be in the same place.

Below the seat post tucked in behind the battery connector.

I’ve always wondered if wireless pressure transducers like those used in automotive tire valves could be attached to bike pedals in a way to gauge how much force the rider is putting into pedaling. It would be a way to achieve torque sensing pedal assist.

Fix the speedometer and report back

Good to have you back Dan. You may have gone to the dark side but we know you still have a wealth of knowledge for us electron lovers. Pop in and share your wisdom whenever you can.

Funny, I never thought about having to purchase packaged sand but I’m a desert dweller and it isn’t hard to find here in Arizona. It doesn’t need to be pure, any loose dry dirt will smother a fire. Yes those are the bamboo sticks I use. very handy to have when soldering or spot welding small...

Interesting project Jared, hope to hear how it works. My thought is that adding a small battery to the circuit to buffer the fluctuations in solar output would help protect the motor from heating up in near stall conditions and provide a bit smoother and more predictable performance.

I put together my first ebike back in 2010. It was a Walmart granite peak mountain bike with a front hub motor and 30 pounds of lead on the rear rack. It was an ungainly piece of crap but I immediately fell in love with the feeling of cruising silently and getting some exercise without giving...

It would be interesting to know how you regulate the three motors. Are they linked to a single throttle? I have dual motor Big Dummy cargo bike with a BBS02 mid drive and a geared front hub. I couldn’t get the two motors to play well together using a shared throttle so I set it up to use pedal...

Fechter, as another victim of too many calendars past, I’m hoping you will elaborate on the success of the mobility device excuse. Would it help to carry a letter from a MD? There are places where the rules change on fire roads and trails as they cross jurisdictional boundaries and you can find...

Sounds like the battery is out of balance and the BMS is shutting it off under load. The display will stay on for a short period of time until the capacitors bleed off. When you let off the throttle the BMS resets.

Thanks for posting Reloader, that looks like an interesting trail that I wasn’t aware of. I may have to put it on my bucket list. If you make the ride I would like to read about it from an ebikers perspective. Things like camping spots, distances between charging locations, trail conditions etc.

I have always assembled the parallel cell groups first and set them aside until all of them are ready for the final assembly in series. These individual groups are less than 4.2 volts and can handled without gloves. It isn’t until you start connecting then in series that there starts to be a...
